The dredge contractors for the Hopper Dredge Disposal Area (HDDA), Great Lakes Dredge and Dock (GLDD) completed dredging at 2146 hours on September 10, 2021.  GLDD representatives have confirmed that they are prepared to commence pipeline removal operations in accordance with the following conditions.  The first complete channel closure will be Tuesday, September 14th from 0600 hours to 1800 hours – the closure may not require full-time.  Traffic will be resumed with communications between GLDD and navigation stakeholders (Pilots and trade representatives) and the appropriate government agencies.
